Leveling kit - 2020 TSS Tundra

I’m looking at getting a leveling kit or some people reference it as a 2-3” lift in the front. The plan is to install the 6112 Bilstein Suspension kit for the front which leaves the rear the same height and will replace the rear shocks for the Bilstein 5100! So aligned, mounted and balance of the tires = $1,900.00 out the door.
Questions:
1) Is this a good deal for $1,900 without the tires? I’m buying tires, BF Goodrich KO3 295/65r20s so just paying for kit and rear shocks.
2) Do I need shackles? Someone else added +3 Coachbuilder shackles and the guy said not need but can add?
3) Control arms - he also said not need for this?
